BACKGROUND

[0002] Motion theaters, of many design forms, physically move the guest from a starting

/ loading position into a projected show environment, with the objective primarily being the sensation of immersion into that environment.

[0003] Many suspended theater designs, up to this point, have been based on a literal suspension of seating apparatus, usually by way of cables, counterweights and winches, and usually from an overhead framework and set of sheaves. Other related products, commonly referred to as“flying theaters,” frequently rely on a moving overhead frame or pivoting floor which translates the seats into the theater environment.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0018] In general, as will be understood by one of ordinary skill in theater seating arts especially for immersive theaters, instead of equipment being above guests, which increases facility height and safety issues, or beneath guests, which also increases facility height, the theater seating assemblies claimed herein lift left and right sides of seat rows by using left and right versions of two otherwise identical machines, as described herein. The result of this arrangement can minimize facility height.

[0019] Moreover, in the described embodiments, rather than the seat rows being pivoted up with a rotating floor, a second function alters their mutual positions relative to one another while the lift function is taking place such as by rotation. This rotate function brings the back seat rows up and over the front seat rows, allowing control over mutual row position during lift and in the show. The rotate function can also allow the seat rows to flatten out, front to back, in order to“hop” over a lower theater screen or wall during lift, and then achieve their final vertical relationship once past that hurdle.

[0020] In a first embodiment, referring generally to Fig. 1, theater seating assembly 1 typically comprises one or more seat support bases 210a, 210b,210c,201d; first seat support 200a; second seat support 200b disposed distally from the first seat support 200a along seat support bases 210a, 210b,210c,201d in a mirror configuration with respect to a seat axis defined by a longitudinal distance between first seat support 200a and second seat support 200b; passenger seat assembly 260 operatively connected to first passenger seat beam rotator 240a and to second passenger seat beam rotator 240b where passenger seat assembly 260 is disposed substantially parallel to the seat axis and comprises a passenger seating area (such as callout 163 in Fig. 2); and one or more system controllers 201,202 operatively in communication with first lift arm actuator 221a, second lift arm actuator 221b, first passenger seat beam rotator actuator 241a, and second passenger seat beam rotator actuator 241b.

First passenger seat beam rotator actuator 241a is operative to effect a change in passenger seat row pitch independently of rotation of first lift arm 220a.

[0022] Second seat support 200b typically mirrors first seat support 200a and comprises second lift arm 220b which is pivotally connected to seat support base 210c,210d; second lift arm actuator 221b which is operatively, and typically pivotally, connected to second lift arm 220b and to seat support base 210c, 20 Id, and typically pivotally, where second lift arm actuator 221b is configured to coordinate movement of second lift arm 220b with movement of first lift arm 220a; second passenger seat beam rotator 240b which is operatively connected to second lift arm 220b, typically pivotally; and second passenger seat beam rotator actuator 241b which is operatively connected to second passenger seat beam rotator 240b distally from the seat support base 210c,210d. Second passenger seat beam rotator actuator 241b is also operative to effect a change in passenger seat row pitch independently of rotation of second lift arm 220b cooperatively with first passenger seat beam rotator actuator 241a.

[0023] A first X-Y plane is defined by seat support base 210a, 201b and first lift arm 220a and a second X-Y plane is defined by seat support base 210c,210d and second lift arm 220b where the second X-Y plane is substantially parallel to the first X-Y plane.

[0026] In this embodiment, passenger seat beam rotator actuator 24 la, 24 lb typically comprises one or more rotary motors which move passenger seat assembly 260 via passenger seat beam rotators 240a, 240b to directly impart pitch to seat beams 260a, 260b relative to pitch rotators 240a, 240b so that pitching the upper row, e.g. 260a, causes the front row, e.g. 260b, to synchronously pitch. Where rotary motors are used, pitch rotators 240a, 240b may further comprise a chain or sprocket set 242a, 242b. In certain contemplated embodiments, each row 260a, 260b may be pitched by its own pair of motors, obviating the mechanical interconnection.

[0027] System controller 201,202 is operative to control and coordinate movement of first lift arm 220a and second lift arm 220b in their respective X-Y planes while simultaneously effecting a change to a pitch angle of passenger seat assembly 260.

Typically, one or more safety encoders 280 are disposed at predetermined locations, typically at or near joints of seat beam rotator 240a, 240b.

[0030] Further, in this embodiment one or more sensors 281,282 may be present and operatively in communication with system controller 201,202 where sensors 281,282 are operative to provide a measurement of a predetermined physical characteristic of first lift arm 220a or second lift arm 220b such as pressure transducer 281, linear transducer 282, or the like, or a combination thereof. Typically, sensors 281,282 are used to monitor and report lift arm positions to help ensure that they are in sync with each other.

[0031] Where motors 241a, 242b and/or 221a, 221b are used, each may be safety encoders

280 and/or sensors 281,282 may be used to help monitor the rotation output of an associated motor 241a, 242b and/or 221a, 221b. [0032] In contemplated versions of this embodiment, one or more brakes (not shown in the figures) may be present and operatively connected to first lift arm 220a or second lift arm 220b, where the brake is operative to impede motion of first lift arm 220a and/or second lift arm 220b. Brakes may impart braking action to a motor, a shaft rotated or translated by a motor, or a disk or other feature designed to receive such action. In other embodiments, braking may more- or-less passive and be accomplished by the normal state of electrical motors with power removed, or the physical characteristics of hydraulic properties when under pressure.

[0033] In contemplated versions of this embodiment, one or more motion dampers

22 la, 22 lb may be present and operatively connected to seat support base 210a,210b,210c,210d, first lift arm 220a, and/or second lift arm 220b.

First passenger seat pitch actuator 140a and the plurality of arm actuators 130, if present, are operative to cooperatively effect changes to the pitch angle of passenger seat assembly 160 an maintain the same pitch angle of passenger seat assembly 160 at first lift arm 120a relative to seat support base 110 with respect to the pitch angle of passenger seat assembly 160 at second lift arm 120b relative to seat support base 110.

[0039] Moreover, in this embodiment passenger seat row rotator 150 further comprises one or more passenger seat row rotator pitch cranks 152 pivotally connected to at least one of first lift arm 120a and second lift arm 120b proximate attachment arm ends 121b, 121d of its respective arm and to passenger seat row rotator actuator 151 pivotally connected to at least one of first lift arm 120a and second lift arm 120b at a first end of passenger seat row rotator actuator 151 and pivotally connected to passenger seat row rotator pitch crank 152 at a second end of passenger seat row rotator actuator 151.

[0040] In this embodiment, passenger seat assembly 160 is similar to that which was described above and further comprises one or more seat beams 161 and at least one passenger seat 162 connected to seat beam 161. In this embodiment, however, passenger seat assembly 160 further comprises first seat beam hanger 600 pivotally connected to first lift arm 120a proximate first lift arm attachment end 121b at an upper seat beam hanger end 601 and to an end of seat beam 161 closest to first lift arm 120a as well as second seat beam hanger 600 pivotally connected to second lift arm 120b proximate second lift arm attachment end 12 Id at an upper seat beam hanger end 601 and to an end of seat beam 161 closest to second lift arm 120b. Where passenger seat assembly 160 comprises two seat beams 161, each seat beam hanger 600 of the seat beam hangers 600 typically further comprises upper seat beam hanger crank 602 pivotally connected to arm attachment end 121b, 121d of its respective arm; lower seat beam hanger crank 604; and seat beam hanger link 605 pivotally connected at a first seat beam hanger link end to the upper seat beam hanger crank and pivotally connected at a second seat beam hanger link end to the lower seat beam hanger crank, where the upper seat beam hanger crank and the lower seat beam hanger crank are operative to maintain substantially identical rotation of each seat beam 161 with respect to each other about their respective passenger seat row axis.

Typically, rotator arm limiter 32e comprises a channel or feature of the joint, such that over-rotation is mechanically prevented by a surface on the rotator arm coming into contact with an opposing surface on lift arm 140, near the pivotal joint by which they are connected. Alternatively, the limiter comprises a feature within the actuator, such as a mechanical hard stop at ends of travel, or a limit switch or sensor which detects a limit in motion. There is a plan to include physical hard tops as a redundant safety measure. The first method of control will be through programming limits. A limit switch might also be used to trigger the end of travel.

[0046] Second side lift 20 is typically substantially identical to first side lift 20 and therefore its description and callouts are the same or highly similar.

[0047] In this embodiment, rotator arm 32 may further comprise rotator arm limiter 32e configured limit angular travel of rotator arm 32 about its rotator arm actuator joint 32c in a plane defined by its associated lift arm 20.

[0051] In any of these embodiments, one or more masses may be associated with each lift arm and disposed on a side of the lift arm’s seat support base bearing axis as a counterbalance.

[0052] In any of these embodiments, mechanical assistance may be incorporated with lift arm actuators 22,221 so as to reduce energy consumption, e.g. one or more spring assemblies, pneumatic cylinders, or hydraulic cylinders (which communicate with one or more nitrogen- filled vessels) disposed proximate to, and configured to act in association with and for the alleviation of load upon, the lift arm actuators 22,221.

[0053] Referring now to Figs. 5 and 6, immersive theater system 100 comprises theater housing 102; theater seating assembly 1, as described in any of the embodiments above, disposed at least partially within theater housing 102, and one or more audiovisual projectors 103 operatively in communication with system controller 70,201,202 (Fig. 1). Typically, seat row beams 161,261 (Fig.l, Fig. 2) extend outward and through aisle area 107 on each side of theater seating assembly 1 into left and right equipment spaces 104 where they then attach to their respective rotators 140,240 (Fig.l, Fig. 2). As used herein, an audiovisual projector may be a video projector, a combined video-sound system with speakers, or the like, or a combination thereof.

[0054] Referring additionally to Fig. 13, in certain configurations of this embodiment, immersive theater system 100 comprises floor 101 where a portion of floor 101 may be configured to be elevated with respect to one or more seat row beams 161,261 (Fig.l, Fig. 2) such as to promote shielding of dropped objects from an upper passenger seat to a lower passenger seat. As also noted above, a canopy (not shown in the figures) may be present and fixed over each passenger seat 162 which moves with its associated passenger seat 162. Additionally, floor 101 may comprise nesting slot or channel 105 which can accommodate all or a portion of seat row beams 161,261 (Fig.l, Fig. 2).

[0055] In the operation of exemplary methods, as will be understood by one of ordinary skill in theater seating art, reference below to“an” embodiment, unless noted otherwise, is applicable, but not limited to, to other embodiments discussed above.

[0056] Referring back to Fig. 1 and Figs. 5-6, a theater experience, typically an immersive theater experience, may be accomplished using theater system 1 as described above by positioning first seat support 200a and second seat support 200b and rotating passenger seat assembly 260 to a passenger boarding position sufficient to allow a passenger to sit in passenger seat assembly 260 (Fig. 13). System controller 70,201,202 substantially synchronously controls first seat support 200a and second seat support 200b and their associated passenger seat beam rotators 240a, 240a via their associated seat beam rotator actuator 24 la, 24 lb to effect a motion between each lift arm 220a, 220b and its associated actuator 22 la, 22 lb such as by adjusting the angular relationship between a lift arm lowered position (Fig. 11, 13) to a lift arm raised position (Figs. 7-10) at a first predetermined set of times. Rather than pivoting passenger seat assembly 260 with a rotating floor, positions of passenger seat assembly 260 are thus altered while a raising and/or lowering function is taking place. Effecting the pitch change typically occurs at a time from the second predetermined set of times when first lift arm 220a and second lift arm 220b are being raised or lowered.

[0057] Typically, arm actuators 22 la, 22 lb are as described above and operative to effect movement in first lift arm 220a in a first X-Y plane defined by seat support base 210a,210b and first lift arm 220a and cooperatively effect substantially identical movement of second lift arm 220b in a second X-Y plane defined by seat support base 210c,210d and second lift arm 220b where the second X-Y plane is substantially parallel to the first X-Y plane. Movement effected by passenger seat beam rotators 240a, 240b is operative to change a pitch angle of passenger seat 260 about the passenger seat row axis. In most embodiments, system controller 70,201,202 is operatively in communication with arm actuators 22 la, 22 lb and passenger seat beam rotators 240a, 240b and coordinates movement of first lift arm 220a and second lift arm 220b in their respective X-Y planes while simultaneously effecting a change to the pitch angle.

[0058] In embodiments wherein floor 101 (Fig. 13) further comprises nesting slot or channel 105 (Fig. 13) configured to accept seat row beam 260a, 260b therein, seat row beam 260a, 260b closest to nesting slot 105 may be nested into nesting slot 105 in a first position, thereby hiding that seat row beam 260a, 260b from audience view while in this lowered load/unload first position.

[0059] Referring again to Fig. 6, immersive theater system 100 typically further comprises one or more audiovisual projectors 103 as described above and movement of first seat support 200a and second seat support 200b, as well as rotation of passenger seat assembly 260, is coordinated with audiovisual projector 103. Thus, the first predetermined set of times and the second predetermined set of times are typically programmed to coincide with a human perceptive presentation such as from or in coordination with projection from audiovisual projector 103.

[0060] At times, a surge front to back translation may be provided or imparted while seat supports 200a, 220b are in a raised show position by combining the motions of lift and rotate. Further, the pitch function may be used to maintain passenger seat assembly 260 at a predetermined position with positive and negative pitch available in a raised or show position.

[0061] If passenger seat assembly 260 comprises a plurality of seat beams, e.g. first seat beam 260a and second seat beam 260b as described above, a rotate function may be controlled using system controller 70,201,202 to bring one seat beam of seat row beams 260a, 260b and its associated passenger seats 163 (Fig. 2) up and over a second set of seat row beams 260a, 260b and its associated passenger seats 163, thereby allowing control over mutual row position during lift and during a show. Additionally, as illustrated in Figs. 7-12, the rotate function may be used to allow seat row beams 260a, 206b and their associated passenger seats rows 163 to flatten out, such as from front to back, in order to“hop” over a lower theater screen or wall during lift and achieve a predetermined final vertical relationship once past that hurdle. Also, a second function may be performed, e.g. via command from system controller 70,201,202, to alter mutual positions of seat row beams 260a and their associated passenger seats 163 relative to one another while a lift function is taking place.

[0062] In certain of the embodiments discussed above, pitch of individual seat row beams 260a, 260b and their associated passenger seats 163 may be controlled in both a forward and a backward motion by forcing rotation of seat row beam hangers 600 on each seat row beam’s ends relative to floor, if seat row beam hangers 600 are present.

[0063] In a further embodiment, referring now generally to Figs. 7-10, an immersive theater experience for an immersive theater system may be provided by using the system controller to command the rotate actuators 40, pitch actuators 28, and lift actuators 22 to position the seat actuator to a first position; controlling left and right lift arm rotator arms 32 via their associated actuators 40 to effect a motion between each lift arm 20 and its associated rotator arm 32 to adjust an angular relationship between the two by adjusting the angular relationship between a first lift arm lowered position to a second lift arm raised show position (Figs. 7-10); and, rather than pivoting seat row beams 161 and their associated passenger seats 162 with a rotating floor, altering mutual positions of seat row beams 161 and their associated passenger seats 162 relative to one another while a lift function is taking place with respect to lift arms 20 such that a rotate function brings a second set of seat row beams 161 of seat row beams 161 and its associated passenger seats 162 up and over a second set of seat row beams 161 and its associated passenger seats 162, thereby allowing control over mutual row position during lift and during a show. The rotate function provided by rotator arms 32 may be used to allow the sets of seat row beams 161 and their associated passenger seats 162 to flatten out, front to back, in order to“hop” over a lower theater screen or wall during lift and achieve a predetermined final vertical relationship once past that hurdle.

[0064] In addition, a second function may be performed to alter mutual positions of the sets of the seat row beams 161 and their associated passenger seats 162 relative to one another while the lift function is taking place. [0065] As with other methods, where floor 101 (Fig. 13) further comprises nesting slot

105 configured to accept seat row beam 161, seat row beam 161 may be nested or otherwise received into nesting slot 105 in a first position, thereby hiding seat row beam 161 from audience view while in a lowered load/unload first position.

[0066] In addition, pitch of individual seat row beams 161 and their associated passenger seats 162 may be controlled, typically in both forward and backward directions, by forcing rotation of seat row beam hangers 31 on each seat row beam’s ends relative to facility floor 101. This is typically accomplished using system controller 70,201,202 and may be further in conjunction with projectors 103 such as during a show.

[0067] Other functions may be controlled as well. By way of example and not limitation, a surge front to back translation may be imparted while lift arms 20 are in a raised show position by combining the motions of lift and rotate. By way of further example and not limitation, the pitch function be used to maintain passenger seats 162 at a predetermined position with positive and negative pitch available in the raised show position.

[0068] As described herein, in embodiments the first and second lift arms, e.g. 20, have a pivotal joint with a passenger seat beam rotator which is controlled by one or more, preferably linear, actuators or rotary motors. The action of these actuators/motors is between the arms and their associated passenger seat beam rotator, adjusting the angular relationship between the two.

[0069] Though no cables are involved, the theater seating assembly described herein still employs seating that is suspended, by way of the seat beams to which each passenger seat is attached. In embodiments, as also described herein, the theater seating assembly can provide controlled pitch of individual seat rows, both forward and backward, such as by forcing rotation of the hangers on each seat row beam’s ends. This rotation is relative to the facility floor, and not the lift arm or rotator. Most embodiments are agnostic of seating type placed upon its beams. For example, it can support individual or banks of motion-seat support base seats or rows of static seats having no further motion.

[0070] The foregoing disclosure and description of the inventions are illustrative and explanatory. Various changes in the size, shape, and materials, as well as in the details of the illustrative construction and/or an illustrative method may be made without departing from the spirit of the invention.
